TIAA-CREF is pleased to help the employees of University of Iowa plan for retirement. For nearly 90 years, we have been helping millions of people in the academic, medical, cultural and research fields plan for retirement. We offer you options to tailor your plan to your investment style and goals.

Life can be complicated, but planning for retirement doesn't have to be. To help you plan for your goals, we offer:

• Sound guidance. Speak with a TIAA-CREF consultant for answers that make sense for you.
• Retirement choices that suit your style.
• A simplified "one decision" strategy. You pick one from a series of new Lifecycle Funds targeted to your expected year of retirement.
• A "Build your own portfolio" strategy. You create your own long-term portfolio from a wide range of investment choices. You can refer to sample portfolios showing various risk tolerance levels.
• Low cost. TIAA-CREF is committed to keeping costs low, with expenses that are among the lowest in the variable annuity and mutual funds industries¹.
• Top ratings. For its stability, sound investments, claims-paying ability and overall financial strength, TIAA is one of only three companies to hold top ratings from the four leading insurance ratings agencies: A.M. Best Co. (6/2007), Fitch (5/2007), Moody's Investors Service (5/2007) and Standard & Poor's (7/2007). Ratings apply only to TIAA as an insurance company, not to CREF or the TIAA Real Estate Account. The ratings do not apply to the performance and safety of the variable accounts.

If you are new to the University of Iowa Retirement Plans, you must first enroll to take advantage of these investment strategies.
